Added support for remote + passworded access

Browse Source 
This password encoder was decompiled from the Android app then manually cleaned up and ported to Javascript. It ain't pretty, but it works.

I don't know that this is all necessarily the most correct or idiomatic way to implement these features, but I wanted to make sure the functionality got committed to help out people wanting to use this for smart home appliances (#1).
